Osbertia

Osbertia is a genus of flowering plants belonging to the family Asteraceae. It is native to North America, specifically found in the southwestern United States and northern Mexico. The genus comprises herbaceous perennial plants, characterized by their yellow disc flowers and absence of ray flowers, thus appearing discoid.

Osbertia species are adapted to arid and semi-arid environments, often found growing in rocky slopes, canyons, and mesas. They are typically relatively small plants, reaching heights of up to approximately 60 centimeters.

The genus is named in honor of Osbert Salvin, a 19th-century English naturalist and ornithologist who made significant contributions to the study of Central American flora and fauna.

Species within the Osbertia genus include:

• Osbertia chihuahuensis
• Osbertia heleniastrum
• Osbertia stolonifera

These plants are of ecological importance within their native ranges, providing resources for pollinators and contributing to overall biodiversity. Further research into their potential medicinal or economic uses may be warranted. The taxonomic classification and relationships within the Osbertia genus have been the subject of some debate, and ongoing studies are helping to clarify the evolutionary history of these plants.
